Question

Determine if the triangles are similar.

A. Yes, SSS
B. Yes, SAS
C. Yes, AA
D. No, not similar

Answer 1

D. No, not similar

ΔFNY: 8<10<12 ⇔ FN<NY<FY

ΔWRY: 14 <18<21 ⇔ WR<YW<YR

`(FN)/(WR) = (8)/(14) = (4)/(7)`

`(NY)/(YW) = (10)/(18) = (5)/(9)`

`(FY)/(YR) = (12)/(21) = (4)/(7)`

`(FN)/(WR) = (FY)/(YR) \bf \\eq (NY)/(YW)`
